How long has it been since dieting? There are noticeable changes in the face

Facial changes after dieting usually take 2-4 weeks to manifest, and the actual time is closely related to basal metabolic rate, body fat distribution, water balance, nutrient intake, and individual differences.

1. Basal metabolic rate: People with high basal metabolism have faster fat breakdown and earlier facial contour changes. Individuals with high muscle mass may initially exhibit temporary facial depression caused by water loss, rather than fat loss, due to sufficient glycogen reserves. Suggest monitoring changes in basal metabolic values through a body fat scale.

2. Body fat distribution:

Facial fat belongs to the superficial distribution of subcutaneous fat, which is more difficult to consume compared to visceral fat. Due to the influence of estrogen, women usually retain facial fat for 1-2 weeks longer than men. Due to the presence of brown adipose tissue in the lower jaw area such as the double chin, improvement may occur first.

3. Water balance:

During the initial 3-5 days of extreme dieting, facial swelling may worsen due to sodium ion imbalance, followed by dehydration induced facial depression due to glycogen depletion. Drinking less than 1.5 liters of water per day can delay the excretion of metabolic waste and make skin sagging more pronounced.

4. Nutritional intake: When the protein intake is less than 0.8 grams per kilogram of body weight, the synthesis of facial collagen is hindered, and skin collapse may occur instead of a healthy lean face. Vitamin C deficiency can lead to increased fragility of capillaries, exacerbating dark circles and facial dullness.

5. Individual differences:

People under the age of 25 have better skin elasticity and their facial changes are 30% -40% faster than middle-aged and elderly people. Individuals with previous weight loss experiences may experience adipocyte memory effects, with a delay of about one week in lower body changes for the same dieting intensity.

Healthy weight loss recommendation: Control weight loss by 0.5-1 kilogram per week, and combine it with facial massage to promote lymphatic circulation. Consuming sufficient amounts of high-quality protein such as eggs and fish, and supplementing with vitamin E and zinc elements can help maintain skin elasticity. Aerobic exercise combined with facial muscle training can shape a clearer jawline, and 10 minutes of head up and mouth opening exercises every day can prevent skin sagging. When experiencing persistent dizziness or menstrual disorders, extreme dieting should be stopped immediately.
